From 17ee0e400bef47c371afcae76037f9ea6a44ad13 Mon Sep 17 00:00:00 2001 From: William Carroll Date: Mon, 10 Sep 2018 14:51:14 -0400 Subject: Support Vim, Tmux, Emacs with Stow After moving off of Meta, Dotfiles has a greater responsibility to manage configs. Vim, Tmux, and Emacs are now within Stow's purview. --- .../elpa/magit-20180719.1904/magit-mode.el | 1360 ++++++++++++++++++++ 1 file changed, 1360 insertions(+) create mode 100644 configs/shared/emacs/.emacs.d/elpa/magit-20180719.1904/magit-mode.el (limited to 'configs/shared/emacs/.emacs.d/elpa/magit-20180719.1904/magit-mode.el') diff --git a/configs/shared/emacs/.emacs.d/elpa/magit-20180719.1904/magit-mode.el b/configs/shared/emacs/.emacs.d/elpa/magit-20180719.1904/magit-mode.el new file mode 100644 index 000000000000..22dced2f6fb9 --- /dev/null +++ b/configs/shared/emacs/.emacs.d/elpa/magit-20180719.1904/magit-mode.el @@ -0,0 +1,1360 @@ +;;; magit-mode.el --- create and refresh Magit buffers -*- lexical-binding: t -*- + +;; Copyright (C) 2010-2018 The Magit Project Contributors +;; +;; You should have received a copy of the AUTHORS.md file which +;; lists all contributors.

All text (for hunk-internal +regions) or the headings of all sections (for sibling selections) +that are inside that range (not just inside the region) are acted +on by commands such as the staging command. This buffer range +begins at the beginning of the line on which the region begins +and ends at the end of the line on which the region ends. + +Because Magit acts on this larger range and not the region, it is +actually quite important to visualize that larger range. If we +don't do that, then one might think that these commands act on +the region instead. If you want to *also* visualize the region, +then set this option to t. But please note that when the region +does *not* constitute a valid selection, then the region is +*always* visualized as usual, and that it is usually under such +circumstances that you want to use a non-magit command to act on +the region. + +Besides keeping the region overlay, setting this option to t also +causes all face properties, except for `:foreground', to be +ignored for the faces used to highlight headings of selected +sections. This avoids the worst conflicts that result from +displaying the region and the selection overlays at the same +time. We are not interested in dealing with other conflicts. +In fact we *already* provide a way to avoid all of these +conflicts: *not* changing the value of this option. + +It should be clear by now that we consider it a mistake to set +this to display the region when the Magit selection is also +visualized, but since it has been requested a few times and +because it doesn't cost much to offer this option we do so. +However that might change.
